Özet

The Virtual Reference Station (VRS) method utilizes a virtual station located just a few meters away from the traveling receiver,

without the need for additional equipment. In this method, the observation data for the virtual reference station point are generated

using data from the surrounding reference stations, as if the instrument was placed at the virtual reference station. Virtual Reference

Station networks employ real-time kinematic solutions to achieve high accuracy. In this study, the coordinates obtained from the

CORS-VRS network were compared with those obtained using a static technique for the same points in a forested environment. The

results of the experiment show that CORS-VRS can achieve 1-2 cm horizontal accuracy and 2-5 cm vertical accuracy in forested

areas. Despite the challenges posed by the tree canopy and signal loss, the results indicate that the CORS-VRS technique improves

positioning accuracy in forested environments.
